## What is Crumb?

Photograph your loaf. Read your dough. Bake better.

Crumb is the sourdough companion that finally tells you what your crumb means. Cut your loaf, photograph the crumb, and Crumb reads it back to you — proofing, hydration, gluten development, hole structure — in plain language, with the one adjustment to make next time. No more guessing why your bread came out dense.

WHY BAKERS USE CRUMB

• Crumb photo analysis — the killer feature. Snap the cut face and get an honest read: under-proofed, over-proofed, well-proofed, or under-hydrated, with a clear next-bake fix.
• Starter log — name your starter, track feedings, hydration, and peak times so you always feed at the right moment.
• Bake builder with timed stages — autolyse, bulk, shape, cold proof, bake — laid out like a workshop wall chart with reminders, so the long proofs never catch you off guard.
• Bake history — every bake with photos, flour mix, hydration, notes, and its crumb assessment in one place.
• Pattern surfacing — across your bakes, Crumb shows what's working: "Your 78% hydration loaves score higher on crumb than your 72% bakes."
• Share cards — generate a clean bake card with your crumb, hydration, flour blend, and verdict. Built for Instagram and r/Sourdough.

NEW IN CRUMB 2.0

• NEW — Trends dashboard: watch your baking get better. Crumb-score over time, score-by-hydration, fault frequency, and your starter's peak-time drift by season, with a plain-language read on the data.
• NEW — Bake reports: export a beautiful PDF of any bake (or a whole-season report) for your kitchen binder or to share with a baking friend.
• NEW — iCloud sync (Pro): your starters, bakes, recipes, and crumb photos follow you across iPhone and iPad.
• NEW — Apple Watch companion (Pro): glance at the current stage, advance a step, or log a feeding — flour-free, from your wrist.
• NEW — Home & Lock Screen widgets (Pro): next step at a glance, plus smart feeding reminders that learn when your starter peaks.
• NEW — Siri & Shortcuts (Pro): "Hey Siri, when does my bake go in the fridge?"

THE CRUMB READ IS THE PRODUCT

Every other app is a timer or a recipe list. Crumb is the only one that looks at the bread you actually made and teaches you from it. The result screen reads like a book plate — your crumb, with elegant callouts on what each feature tells you. Honest, too: an assessment is a starting point, not a verdict. Bake by feel; Crumb helps you read what you made.
